Participants

Reaction Steps

An ice cooled solution of (3-(benzyloxymethyl)oxetan-3-yl)methanol (Example 44E, 1.00 g, 4.80 mmol) in DCM (5.14 mL) was treated with triethylamine (1.31 mL, 9.43 mmol) and methanesulfonyl chloride (0.438 mL, 5.66 mmol) and gradually allowed to warm up to rt over 16 hrs. The mixture was diluted with DCM, washed with saturated aqueous NaHCO3 solution (1×), brine (2×), dried over anhydrous sodium sulfate, filtered, concentrated in vacuo to a solid to afford 7.2 g of the title compound (100%). The crude product was used in next step without further purification. 1H NMR (400 MHz, CD3OD) δ 7.23-7.38 (m, 5H), 4.58 (s, 2H), 4.46-4.54 (m, 6H), 3.74 (s, 2H), 3.09 (s, 3H).
